DESCRIPTION
The Texas Instruments MSP430™ family of ultralow-power microcontrollers consists of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with extensive low-
power modes, is optimized to achieve extended battery life in portable measurement applications. The device
features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code
efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active
mode in 3.5 µs (typical).
The MSP430F543xA and MSP430F541xA series are microcontroller configurations with three 16-bit timers, a
high-performance 12-bit analog-to-digital converter (ADC), up to four universal serial communication interfaces
(USCIs), a hardware multiplier, DMA, a real-time clock module with alarm capabilities, and up to 87 I/O pins.
Typical applications for this device include analog and digital sensor systems, digital motor control, remote
controls, thermostats, digital timers, and hand-held meters.

Device and Development Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
MSP430™ MCU devices and support tools. Each MSP430™ MCU commercial family member has one of two
prefixes: MSP or XMS (for example, MSP430F5259). Texas Instruments recommends two of three possible
prefix designators for its support tools: MSP and MSPX. These prefixes represent evolutionary stages of product
development from engineering prototypes (with XMS for devices and MSPX for tools) through fully qualified
production devices and tools (with MSP for devices and MSP for tools).
Device development evolutionary flow:
XMS – Experimental device that is not necessarily representative of the final device's electrical specifications
MSP – Fully qualified production device
Support tool development evolutionary flow:
MSPX – Development-support product that has not yet completed Texas Instruments internal qualification
testing.
MSP – Fully-qualified development-support product
XMS devices and MSPX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
MSP devices and MSP development-support tools have been characterized fully, and the quality and reliability of
the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (XMS) have a greater failure rate than the standard production devices.
Texas Instruments recommends that these devices not be used in any production system because their
expected end-use failure rate still is undefined. Only qualified production devices are to be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type
(for example, PZP) and temperature range (for example, T). Figure 1 provides a legend for reading the complete
device name for any family member.

Short-Form Description
CPU (Link to User's Guide)
The MSP430 CPU has a 16-bit RISC architecture
that is highly transparent to the application. All
operations, other than program-flow instructions, are
performed as register operations in conjunction with
seven addressing modes for source operand and four
addressing modes for destination operand.
The CPU is integrated with 16 registers that provide
reduced instruction execution time. The register-to-
register operation execution time is one cycle of the
CPU clock.
Four of the registers, R0 to R3, are dedicated as
program counter, stack pointer, status register, and
constant generator, respectively. The remaining
registers are general-purpose registers.
Peripherals are connected to the CPU using data,
address, and control buses, and can be handled with
all instructions.
The instruction set consists of the original 51
instructions with three formats and seven address
modes and additional instructions for the expanded
address range. Each instruction can operate on word
and byte data.
Operating Modes
The MSP430 has one active mode and six software selectable low-power modes of operation. An interrupt event
can wake up the device from any of the low-power modes, service the request, and restore back to the low-
power mode on return from the interrupt program.
The following seven operating modes can be configured by software:
• Low-power mode 3 (LPM3)
• Active mode (AM) – CPU is disabled
– All clocks are active – MCLK, FLL loop control, and DCOCLK are
• Low-power mode 0 (LPM0) disabled
– CPU is disabled – DCO's dc generator is disabled
– ACLK and SMCLK remain active – ACLK remains active
– MCLK is disabled • Low-power mode 4 (LPM4)
– FLL loop control remains active – CPU is disabled
• Low-power mode 1 (LPM1) – ACLK is disabled
– CPU is disabled – MCLK, FLL loop control, and DCOCLK are
– FLL loop control is disabled disabled
– ACLK and SMCLK remain active – DCO's dc generator is disabled
– MCLK is disabled – Crystal oscillator is stopped
• Low-power mode 2 (LPM2) – Complete data retention
– CPU is disabled • Low-power mode 4.5 (LPM4.5)
– MCLK, FLL loop control, and DCOCLK are – Internal regulator disabled
disabled – No data retention
– DCO's dc-generator remains enabled – Wakeup from RST, digital I/O
– ACLK remains active

Bootstrap Loader (BSL)
The BSL enables users to program the flash memory or RAM using a UART serial interface. Access to the
device memory via the BSL is protected by an user-defined password. Usage of the BSL requires four pins as
shown in Table 4. BSL entry requires a specific entry sequence on the RST/NMI/SBWTDIO and TEST/SBWTCK
pins. For complete description of the features of the BSL and its implementation, see the MSP430 Memory
Programming via the Bootstrap Loader User's Guide (SLAU319).

Flash Memory (Link to User's Guide)
The flash memory can be programmed via the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the
CPU. The CPU can perform single-byte, single-word, and long-word writes to the flash memory. Features of the
flash memory include:
• Flash memory has n segments of main memory and four segments of information memory (A to D) of
128 bytes each. Each segment in main memory is 512 bytes in size.
• Segments 0 to n may be erased in one step, or each segment may be individually erased.
• Segments A to D can be erased individually. Segments A to D are also called information memory.
• Segment A can be locked separately.
RAM Memory (Link to User's Guide)
The RAM memory is made up of n sectors. Each sector can be completely powered down to save leakage,
however all data is lost. Features of the RAM memory include:
• RAM memory has n sectors. The size of a sector can be found in Memory Organization.
• Each sector 0 to n can be complete disabled; however, data retention is lost.
• Each sector 0 to n automatically enters low-power retention mode when possible.
• For devices that contain USB memory, the USB memory can be used as normal RAM if USB is not required.
Peripherals
Peripherals are connected to the CPU through data, address, and control buses and can be handled using all
instructions. For complete module descriptions, see the MSP430x5xx and MSP430x6xx Family User's Guide
(SLAU208).
Digital I/O (Link to User's Guide)
There are up to ten 8-bit I/O ports implemented: For 100-pin options, P1 through P10 are complete. P11 contains
three individual I/O ports. For 80-pin options, P1 through P7 are complete. P8 contains seven individual I/O ports.
P9 through P11 do not exist. Port PJ contains four individual I/O ports, common to all devices.
• All individual I/O bits are independently programmable.
• Any combination of input, output, and interrupt conditions is possible.
• Pullup or pulldown on all ports is programmable.
• Drive strength on all ports is programmable.
• Edge-selectable interrupt and LPM4.5 wakeup input capability is available for all bits of ports P1 and P2.
• Read and write access to port-control registers is supported by all instructions.
• Ports can be accessed byte-wise (P1 through P11) or word-wise in pairs (PA through PF).

Oscillator and System Clock (Link to User's Guide)
The clock system is supported by the Unified Clock System (UCS) module that includes support for a 32-kHz
watch crystal oscillator (XT1 LF mode), an internal very-low-power low-frequency oscillator (VLO), an internal
trimmed low-frequency oscillator (REFO), an integrated internal digitally controlled oscillator (DCO), and a high-
frequency crystal oscillator (XT1 HF mode or XT2). The UCS module is designed to meet the requirements of
both low system cost and low power consumption. The UCS module features digital frequency locked loop (FLL)
hardware that, in conjunction with a digital modulator, stabilizes the DCO frequency to a programmable multiple
of the selected FLL reference frequency. The internal DCO provides a fast turn-on clock source and stabilizes in
less than 5 µs. The UCS module provides the following clock signals:
• Auxiliary clock (ACLK), sourced from a 32-kHz watch crystal, a high-frequency crystal, the internal low-
frequency oscillator (VLO), the trimmed low-frequency oscillator (REFO), or the internal digitally controlled
oscillator DCO.
• Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources made
available to ACLK.
• Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by
same sources made available to ACLK.
• ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, ACLK/8, ACLK/16, ACLK/32.
Power Management Module (PMM) (Link to User's Guide)
The PMM includes an integrated voltage regulator that supplies the core voltage to the device and contains
programmable output levels to provide for power optimization. The PMM also includes supply voltage supervisor
(SVS) and supply voltage monitoring (SVM) circuitry, as well as brownout protection. The brownout circuit is
implemented to provide the proper internal reset signal to the device during power-on and power-off. The SVS
and SVM circuitry detects if the supply voltage drops below a user-selectable level and supports both supply
voltage supervision (the device is automatically reset) and supply voltage monitoring (the device is not
automatically reset). SVS and SVM circuitry is available on the primary supply and core supply.
Hardware Multiplier (MPY) (Link to User's Guide)
The multiplication operation is supported by a dedicated peripheral module. The module performs operations with
32-bit, 24-bit, 16-bit, and 8-bit operands. The module is capable of supporting signed and unsigned multiplication
as well as signed and unsigned multiply and accumulate operations.
Real-Time Clock (RTC_A) (Link to User's Guide)
The RTC_A module can be used as a general-purpose 32-bit counter (counter mode) or as an integrated real-
time clock (RTC) (calendar mode). In counter mode, the RTC_A also includes two independent 8-bit timers that
can be cascaded to form a 16-bit timer/counter. Both timers can be read and written by software. Calendar mode
integrates an internal calendar which compensates for months with less than 31 days and includes leap year
correction. The RTC_A also supports flexible alarm functions and offset-calibration hardware.
Watchdog Timer (WDT_A) (Link to User's Guide)
The primary function of the watchdog timer (WDT_A) module is to perform a controlled system restart after a
software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog
function is not needed in an application, the module can be configured as an interval timer and can generate
interrupts at selected time intervals.

DMA Controller (Link to User's Guide)
The DMA controller allows movement of data from one memory address to another without CPU intervention. For
example, the DMA controller can be used to move data from the ADC12_A conversion memory to RAM. Using
the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system
power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or
from a peripheral.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages referenced to VSS. VCORE is for internal device use only. No external DC loading or voltage should be applied.
(3) Higher temperature may be applied during board soldering according to the current JEDEC J-STD-020 specification with peak reflow
temperatures not higher than classified on the device label on the shipping boxes or reels.

(1) It is recommended to power AVCC and DVCC from the same source. A maximum difference of 0.3 V between AVCC and DVCC can be
tolerated during power up and operation.
(2) The minimum supply voltage is defined by the supervisor SVS levels when it is enabled. See the PMM, SVS High Side threshold
parameters for the exact values and further details.
(3) The MSP430 CPU is clocked directly with MCLK. Both the high and low phase of MCLK must not exceed the pulse duration of the
specified maximum frequency.
(4) Modules may have a different maximum input clock specification. See the specification of the respective module in this data sheet.

(1) To improve EMI on the XT1 oscillator, the following guidelines should be observed.
(a) Keep the trace between the device and the crystal as short as possible.
(b) Design a good ground plane around the oscillator pins.
(c) Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
(d) Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
(e) Use assembly materials and techniques to avoid any parasitic load on the oscillator XIN and XOUT pins.
(f) If conformal coating is used, make sure that it does not induce capacitive or resistive leakage between the oscillator pins.
(2) When XT1BYPASS is set, XT1 circuits are automatically powered down. Input signal is a digital square wave with parametrics defined in
the Schmitt-trigger Inputs section of this datasheet.
(3) Maximum frequency of operation of the entire device cannot be exceeded.
(4) Oscillation allowance is based on a safety factor of 5 for recommended crystals. The oscillation allowance is a function of the
XT1DRIVEx settings and the effective load. In general, comparable oscillator allowance can be achieved based on the following
guidelines, but should be evaluated based on the actual crystal selected for the application:
(a) For XT1DRIVEx = 0, CL,eff ≤6 pF.
(b) For XT1DRIVEx = 1, 6 pF ≤CL,eff ≤9 pF.
(c) For XT1DRIVEx = 2, 6 pF ≤CL,eff ≤10 pF.
(d) For XT1DRIVEx = 3, CL,eff ≥6 pF.
(5) Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Since the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency. For a
correct setup, the effective load capacitance should always match the specification of the used crystal.
(6) Requires external capacitors at both terminals. Values are specified by crystal manufacturers.
(7) Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag.
Frequencies in between might set the flag.
(8) Measured with logic-level input frequency but also applies to operation with crystals.

(1) Requires external capacitors at both terminals. Values are specified by crystal manufacturers. In general, an effective load capacitance
of up to 18 pF can be supported.
(2) To improve EMI on the XT2 oscillator the following guidelines should be observed.
(a) Keep the traces between the device and the crystal as short as possible.
(b) Design a good ground plane around the oscillator pins.
(c) Prevent crosstalk from other clock or data lines into oscillator pins XT2IN and XT2OUT.
(d) Avoid running PCB traces underneath or adjacent to the XT2IN and XT2OUT pins.
(e) Use assembly materials and techniques to avoid any parasitic load on the oscillator XT2IN and XT2OUT pins.
(f) If conformal coating is used, make sure that it does not induce capacitive or resistive leakage between the oscillator pins.
(3) This represents the maximum frequency that can be input to the device externally. Maximum frequency achievable on the device
operation is based on the frequencies present on ACLK, MCLK, and SMCLK cannot be exceed for a given range of operation.
(4) When XT2BYPASS is set, the XT2 circuit is automatically powered down. Input signal is a digital square wave with parametrics defined
in the Schmitt-trigger Inputs section of this datasheet.

(5) Oscillation allowance is based on a safety factor of 5 for recommended crystals.
(6) Includes parasitic bond and package capacitance (approximately 2 pF per pin).
Since the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency. For a
correct setup, the effective load capacitance should always match the specification of the used crystal.
(7) Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag.
Frequencies in between might set the flag.
(8) Measured with logic-level input frequency but also applies to operation with crystals.

(1) When selecting the proper DCO frequency range (DCORSELx), the target DCO frequency, fDCO, should be set to reside within the
range of fDCO(n, 0),MAX ≤fDCO ≤fDCO(n, 31),MIN, where fDCO(n, 0),MAX represents the maximum frequency specified for the DCO frequency,
range n, tap 0 (DCOx = 0) and fDCO(n,31),MIN represents the minimum frequency specified for the DCO frequency, range n, tap 31 (DCOx
= 31). This ensures that the target DCO frequency resides within the range selected. It should also be noted that if the actual fDCO
frequency for the selected range causes the FLL or the application to select tap 0 or 31, the DCO fault flag is set to report that the
selected range is at its minimum or maximum tap setting.

(2) The temperature sensor offset can be significant. A single-point calibration is recommended to minimize the offset error of the built-in
temperature sensor. The TLV structure contains calibration values for 30°C ± 3°C and 85°C ± 3°C for each of the available reference
voltage levels. The sensor voltage can be computed as VSENSE = TCSENSOR * (Temperature,°C) + VSENSOR, where TCSENSOR and
VSENSOR can be computed from the calibration values for higher accuracy. See also the MSP430x5xx and MSP430x6xx Family User's

(1) The external reference is used during ADC conversion to charge and discharge the capacitance array. The input capacitance, Ci, is also
the dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the
recommendations on analog-source impedance to allow the charge to settle for 12-bit accuracy.
(2) The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
(3) The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced
accuracy requirements.
(4) The accuracy limits minimum external differential reference voltage. Lower differential reference voltage levels may be applied with
reduced accuracy requirements.
(5) Two decoupling capacitors, 10 µF and 100 nF, should be connected to VREF to decouple the dynamic current required for an external
reference source if it is used for the ADC12_A. See also the MSP430x5xx and MSP430x6xx Family User's Guide (SLAU208).

(1) The reference is supplied to the ADC by the REF module and is buffered locally inside the ADC. The ADC uses two internal buffers, one
smaller and one larger for driving the VREF+ terminal. When REFOUT = 1, the reference is available at the VREF+ terminal, as well as,
used as the reference for the conversion and utilizes the larger buffer. When REFOUT = 0, the reference is only used as the reference
for the conversion and utilizes the smaller buffer.
(2) The internal reference current is supplied via terminal AVCC. Consumption is independent of the ADC12ON control bit, unless a
conversion is active. REFOUT = 0 represents the current contribution of the smaller buffer. REFOUT = 1 represents the current
contribution of the larger buffer without external load.
(3) The temperature sensor is provided by the REF module. Its current is supplied via terminal AVCC and is equivalent to IREF+ with REFON
=1 and REFOUT = 0.

3-wire SPI mode if 4-wire SPI mode is selected.
(6) The secondary function on these pins are reserved for factory test purposes. Application should keep the P10SEL.x of these ports
cleared to prevent potential conflicts with the application.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-
compliance with the terms and provisions of this Notice.
